Solution :

set the below noted environment in context file instead of path set “/u01/app/oracle/db/tech_st/12c/appsutil/clone/jre//bin/java”

the path should be like below

<JDK_TOP oa_var=”s_jdktop”>/u01/app/oracle/db/tech_st/12c/jdk/jre/</JDK_TOP>
<JRE_TOP oa_var=”s_jretop”>/u01/app/oracle/db/tech_st/12c/jdk/jre/</JRE_TOP>

After that, you need to do the autoconfig(adconfig.pl) for database tier and then i tried to run adpreclone.pl, it’s successful.
